The Claim

Creatine supplementation improves mental processing speed in humans.

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

Supports

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Taking creatine supplements increases the speed at which the brain processes information.

Creatine supplementation improves mental processing speed.

What the research says

3 studies

  1. Study: Single dose creatine improves cognitive performance and induces changes in cerebral high energy phosphates during sleep deprivation

    Taking a big dose of creatine helped people who were tired from lack of sleep think faster, showing that creatine can boost brain processing speed.

  2. Study: The Effects of 8-Week Creatine Hydrochloride and Creatine Ethyl Ester Supplementation on Cognition, Clinical Outcomes, and Brain Creatine Levels in Perimenopausal and Menopausal Women (CONCRET-MENOPA): A Randomized Controlled Trial.

    The study found that women who took creatine had faster reaction times than those who took a placebo, meaning their brains processed information more quickly.

  3. Study: The Efficacy of Creatine Supplementation in Improving Cognitive Performance in Adolescents: A Phase-II, Triple-Blind, Randomized Study Protocol

    This study is just a plan—it hasn't been done yet—so we don't know if creatine actually helps with mental processing speed.
